"If the Prince of Conde comes back." What had the Prince of Conde, his comings and his goings, to do with this vast enterprise?

It is time to point to the golden thread of most fantastic passion which runs throughout this dark and eventful history.

One evening in the beginning of the year which had just come to its close there was to be a splendid fancy ball at the Louvre in the course of which several young ladies of highest rank were to perform a dance in mythological costume.

The King, on ill terms with the Queen, who harassed him with scenes of affected jealousy, while engaged in permanent plots with her paramour and master, the Italian Concini, against his policy and his life; on still worse terms with his latest mistress in chief, the Marquise de Verneuil, who hated him and revenged herself for enduring his caresses by making him the butt of her venomous wit, had taken the festivities of a court in dudgeon where he possessed hosts of enemies and flatterers but scarcely a single friend.

He refused to attend any of the rehearsals of the ballet, but one day a group of Diana and her nymphs passed him in the great gallery of the palace. One of the nymphs as she went by turned and aimed her gilded javelin at his heart. Henry looked and saw the most beautiful young creature, so he thought, that mortal eye had ever gazed upon, and according to his wont fell instantly over head and ears in love. He said afterwards that he felt himself pierced to the heart and was ready to faint away.

The lady was just fifteen years of age. The King was turned of fifty-five. The disparity of age seemed to make the royal passion ridiculous. To Henry the situation seemed poetical and pathetic. After this first interview he never missed a single rehearsal. In the intervals he called perpetually for the services of the court poet Malherbe, who certainly contrived to perpetrate in his behalf some of the most detestable verses that even he had ever composed.

The nymph was Marguerite de Montmorency, daughter of the Constable of France, and destined one day to become the mother of the great Conde, hero of Rocroy. There can be no doubt that she was exquisitely beautiful. Fair-haired, with a complexion of dazzling purity, large expressive eyes, delicate but commanding features, she had a singular fascination of look and gesture, and a winning, almost childlike, simplicity of manner. Without feminine artifice or commonplace coquetry, she seemed to bewitch and subdue at a glance men of all ranks, ages, and pursuits; kings and cardinals, great generals, ambassadors and statesmen, as well as humbler mortals whether Spanish, Italian, French, or Flemish. The Constable, an ignorant man who, as the King averred, could neither write nor read, understood as well as more learned sages the manners and humours of the court. He had destined his daughter for the young and brilliant Bassompierre, the most dazzling of all the cavaliers of the day. The two were betrothed.

But the love-stricken Henry, then confined to his bed with the gout, sent for the chosen husband of the beautiful Margaret.

"Bassompierre, my friend," said the aged king, as the youthful lover knelt before him at the bedside, "I have become not in love, but mad, out of my senses, furious for Mademoiselle de Montmorency. If she should love you, I should hate you. If she should love me, you would hate me. 'Tis better that this should not be the cause of breaking up our good intelligence, for I love you with affection and inclination. I am resolved to marry her to my nephew the Prince of Conde, and to keep her near my family. She will be the consolation and support of my old age into which I am now about to enter. I shall give my nephew, who loves the chase a thousand times better than he does ladies, 100,000 livres a year, and I wish no other favour from her than her affection without making further pretensions."

It was eight o'clock of a black winter's morning, and the tears as he spoke ran down the cheeks of the hero of Ivry and bedewed the face of the kneeling Bassompierre.
